Is he purebred or not?

Hey there, I'm new in here and I have a question for you guys. I live Turkey and I found a shaved, male, 8/9 months old dog in street. Now I search a new family for him because I already have a female dog at home and my girl doesn't want him in our house, she is so jealous. I tought he is dark brown labrador retriever only shaved but we meet a family today for adoption and they said he is mixed or something. They didn't want him because of this. And now I'm just curios is he purebred or not. This is not important for me I only want a good family for him because he is soo good boy. Purebred or not it doesn't matter right, but people are so cruel now. His ears a little smaller and not very good shape but a ear massage help him to fix his ears. I hope I'll found a good home for him and he'll always happy with his new family members. My english is not very good so I hope you guys understand me properly.

Hi Buse and welcome to the forum.
Unfortunately, it is against the rules of the forum to request verification of a dog's pedigree by posting pictures. Here is the rule in question:

1.Prohibited content

f) Requests for confirmation of pedigree/ID Forum members may not post photographs of their dogs for the purpose of asking other members to confirm that their puppy/dog is a pedigree dog.

And a link to the rules in their entirety: https://thelabradorforum.com/threads/forum-rules-please-read-before-posting.1599/

Please feel free to continue to use the forum otherwise.
